Well then it should be extremely easy. Just attach 2 servos to your RC receiver and put wheels on them. When you send the command for the left wheel to go forward and the right wheel to go backward, you get a right turn. Same goes for left turns. Just remember the close your servos are mounted to the front of the body, the more you will be swinging the back around. If you want tight turns, mount your servos closer to the center. If you aren't worried about getting the back end caught on walls our out of the ring when turning, mounting them towards the front will help with stability.
